SPECIFICATION forming part of Letters Patent No. 397,210, dated February5, 1889.

Application filed September 21, 1388. Serial No. 285,980. (No model.)

To all whom it may concern.-

Be it known that I, ORRIN T. \V'ELCH, a citizen of the United States,residing at 'l opeka, Shawnee county, State of Kansas,'have inventedcertain new and useful Improvements in Seal-Locks, of which thefollowing is a full, clear, and exact specification.

My invention relates to seal-locks of the class particularly designedfor employment on car-doors or other similar places; and it has for itsobject to provide a simple, cheap, and effective seal, whereby the doormay be read ily locked and unauthorized tampering with the lock oraccess to the car prevented without destroying or defacing the seal, andthereby indicating this fact immediately to the persons in charge.

My invention consists in a seal-lock applied to the ordinary hasp orother fastener, and

constructed and arranged substantially as hereinafter set forth.

Referring to the accompanying drawings, Figure 1 is a plan view showingmy improved lock applied to a car. Fig. 2 is a transverse section on theline 1 1, Fig. 1. Fig. 3 is an inverted perspective view of the lockin gdevice.

In carrying out. my invention I make use of a hasp, A, prcferal'ily insubstantially the form of the ordinary car-hasp, and this is pivotallyconnected at one end by a staple, B, to the door or side of the car, asthe case may be, while the other end is provided with a slot, 0, throughwhich a staple, D, passes, in which staple a pin, E, or other lockingdevice may be secured.

By the use of my improved seal, hereinafter described, a pin is all thatis usually necessary to secure the door, as any attempt to remove thehasp from the staple D sufficient to allow the door to be opened willinsure the breaking of the seal. The body of this hasp is formed with alongitudinal slot, F, which is adapted to fit over a loop or staple, G,secured to the door. This loop in the present instance is shown ashaving a base-piece, and a top piece, g, the two pieces being connectedat the ends, forming a loop or opening for the reception of the seal, ashereinafter explained, and, while I consider this the most practicalconstruction, it is evident that a simple staple may be used. Upon theface of the hasp are cast or otherwise formed a number of projections,u, so arranged as to receive and retain a seal. Two of these projectionsare recessed at their internal corners, while the other two are recessedlaterally, so that the seal maybe slid under the latter two projections,and the corners of the seal will enter the corner recesses of the othertwo projections and be retainedthereby from both cndwise and lateralmotion.

The seal may be made of any suitable material and be provided with anydesired marks or indications. I prefer, however, to use some brittle oreasily-breakable material-such as glass or other vitreous substanceandto impress or otherwise form thereon certain letters or marks toindicate the road upon which they are to be used, a serial. number toindicate the number of the seal, and some ornamental medallion or markor other configuration which is comparatively diffi cult to make, andwhich in itself shall form a distinguishing characteristic of the sealand will aid in preventing the ready counterfeiting thereof.

In order to hold the seal withinthe lugs of the hasp and prevent itswithdrawal after having been properly placed therein, I provide alocking device, II, arranged at one side of the hasp. This lockingdevice may be constructed in different ways to accomplish this purpose;but I have shown in the accompanying drawings what I consider to be amost practical form, in that it is simple and cheap in construction andfurnishes a secure lock, which is practically impregnable tounauthorized opening. This lock consists of a suitable base portion,71., having an elongated eye, 1, adapted to engage a staple, I, securedto the car-door, and elongated to permit a sliding movement of thelocking device. The under side of the base of this locking device isrecessed and is adapted to fit over a block, K, secured to the side ofthe door, and provided with a hole or seat, I, for the reception of thelocking-bolt L. This locking-bolt L is fitted in a recess in the bodyportion of the locking device, which is extended upward for thispurpose, and which extension also furnishes a convenient handle, N, foroperating the device. The bolt is normally under the stress of a spring,M, (shown in the present instance as a coiled spring seated in therecess above and around the bolt,) although it is evident that any otherterm of spring may be used. readily spring into its seat? in the blockK, and forms what ma) be termed a blind-locking device, in that noportion ol. the bolt is exposed to \iew or to the manipulation oflock-picking devices.

The forward portion of the locking device is provided with inclinedextensions 0, which are adapted to lit under the hasp in the mannershown, the hasp being provided with recesses on the underside thereoffor the reception of these elongat-ions, as imlieated by dotted lines inFig. '1.

Such being the construction of the preferred embodiment of my invention, its operation will be readily understood.

Supposing the door to be open, the hasp will hang freely from itspivotal staple H, and the locking device will be supported by its stapleI. The door then beingelosed,thehasp is placed in posit ion by engagingthe staple l), and the loeking-l'iolt isapplied. The seal, which hasbeen previously prepared and is numbered, as before stated, is thenslipped into its position, as shown in l ig. l, passing nndernei'ith thestaple or loop G and resting in the recesses in the projeetimls (1 ofthe hasp. The locking deviee is then brought into position overtheblockK and pressed closely agaii'lst the side ol the car, when the bolt willbe retracted against the stress ot' the spring by coming in contact withthe upper surface. ot the block, and the extensions (7) 0 will comeopposite the recesses on the under side of the hasp. The locking deviceis then pressed downward, forcing the extensions into position, and assoon as this is accomplished the bolt. slips into its seat in the block,being l'orced therein by the spring M, and the seal is effectuallysecured in position in the hasp. It will be seen that the bolt arrangedin this position is protectetil on all sides from the operation of anypi ekin g device, and it cannot be unfasten ed without first removingthe hasp.

As before statm'l, any attempt to open the hasp will be prevented bvtheseal, and it can only be accomplished by first destroying the seal orpressing it against the loop or staple G.

\Vhat I claim is The bolt as thus arranged will= I 1. In a seal-lockingdevice, the combinze tion, with a hasp having projections on the facethereof for holding the seal between the hasp and projections, of alocking device ar ranged at the side of the hasp and adapted to hold theseal in position on the [face of hasp, substantially as described.

1 In a seal-locking device, the combination, with a hasp having alongitudinal slot, of a loop proj eeting through said slot-,a brealeable seal secured upon the hasp and passing through the loop, and alocking device arranged at the side of the hasp to secure the seal,substantially as described.

3. In a seal-locking device, the combination, with a hasp supporting abreakable seal, of a locking device arranged at the side thereof, thesaid device being provided with a bolt and projections to engage withthe hasp, substantially as described.

4. In a seal-locking device, the combination, with a hasp carrying aseal, of a locking device arranged at the side thereof and adapted toengage with theh asp, and provided with i a blind-bolt to engage with afixed seat, substantially as described.

5. In a seal locking device, the combination, with a hasp carrying aseal, of a locking device having a recess in the base thereof, aspring-liiolt supported in said recess, and a fixed block provided witha seat for said bolt device, substantially as described.

6. In a seal-locking device, the combination, with a hasp carrying aseal and having recesses in the underside, of a seal-locking l deviceprovided with projections 0, adapted to engage the said recesses and tobe held in looking position therel'iy, substantially as described.

In testimony whereof I have signed 1n y name to this specification inthe presence of two subscribing witnesses.
